Our architecture, whose schematic is shown on Figure REF , is adapted from [1]}. The precise shape of the encoder is as follows: the filter size of the convolution layers is \([32, 64, 128, 192, 192, 192, 256]\) . Each layer uses a \(3\times 3\)  kernel and is followed by a ReLU activation and an average pooling layer of a factor 2.
